Description

Technical Field

[0001] The present application relates to the field of imaging technology, and in particular to a camera device and a smart terminal. Background Art

[0002] With the increasing popularity of mobile electronic devices, the technology behind camera modules used in these devices to help users capture images has experienced rapid development and advancement. Currently, consumers are demanding increasingly advanced and diverse features from camera modules in mobile devices (e.g., smartphones), such as image stabilization for better imaging.

[0003] When using mobile electronic devices to record video, the normal human body experiences certain frequencies of physiological tremors and jitter caused by movement, which can degrade the quality of the video. This is especially true for ordinary consumers, who lack professional training and are more susceptible to jitter and experience greater amplitude. Therefore, mobile electronic devices are often equipped with an anti-shake motor to drive the optical lens to achieve anti-shake.

[0004] During the process of conceiving and implementing this application, the inventors discovered that there are at least the following problems: the existing anti-shake motors can generally only achieve an anti-shake angle of about 1°, and cannot avoid large-angle anti-shake. In particular, the spring or ball design in the AF direction will generate inertial force in moving scenes, causing the lens to move back and forth and produce a breathing effect problem.

[0047] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication.

It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the smart terminal and can be omitted as needed without changing the essence of the invention.

[0049] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the smart terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the smart terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0050] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0051] The smart terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the panel 1061 and / or the backlight when the smart terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

[0053] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the smart terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using any suitable object or accessory such as a finger, stylus, etc. on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal caused by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0054] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0056] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0057] Processor 110 is the control center of the smart terminal, connecting all components of the smart terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the smart terminal and processes data, thereby providing overall monitoring of the smart terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0058] The smart terminal 100 may also include a power supply 111 (such as a battery) to supply power to each component. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0059] although Figure 1 Not shown, the smart terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0060] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0066] Although the above introduction takes the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but can also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., which are not limited here.

[0067] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0068] First embodiment

[0069] Figure 3 is a structural diagram of the camera device according to the first embodiment of the present application. Figure 4 yes Figure 3 The camera device shown is a schematic structural diagram without the housing and locking mechanism. Figure 5 : is a schematic diagram of the disassembled structure of the camera device according to the first embodiment of the present application. Figure 3 、 Figure 4 and Figure 5As shown, the camera device includes a base 12, a lens carrier 13, and a locking mechanism 14. An elastic structure 15 is connected between the lens carrier 13 and the base 12 to allow the lens carrier 13 to float above the base 12. The locking mechanism 14 is configured to drive the lens carrier 13 to overcome the elastic force of the elastic structure 15 so that the lens carrier 13 abuts against the base 12, thereby locking the lens carrier 13. In this embodiment, the camera device has a super-motion video stabilization mode, which is activated when the camera device is in a high-frequency, intense motion scene and needs to record video. For example, when the camera device enters the video recording mode and is in a high-frequency, intense motion scene, the camera device will experience significant inertial movement, resulting in increased jitter, water ripples, and vibration. To avoid these problems, the locking mechanism 14 drives the lens carrier 13 to abut against the base 12, thereby locking the lens carrier 13. When the camera device is shooting normally, the locking mechanism 14 unlocks the lens carrier 13, allowing the camera device to perform focus and stabilization functions.

[0070] In high-frequency and intense motion scenes, the camera device of the present application can use the locking mechanism 14 to drive the lens carrier 13 against the base 12 to lock the lens carrier 13, which can effectively avoid jitter and high-frequency vibration problems and has a better video anti-shake effect.

[0071] Optionally, the lens carrier 13 is used to mount an optical lens, which is not shown in the above figures.

[0072] Alternatively, as Figure 3 and Figure 5 As shown, the locking mechanism 14 includes a magnet structure 141 and a coil structure 142. The magnet structure 141 is connected to the lens carrier 13, and the coil structure 142 is arranged opposite to the magnet structure 141. When the coil structure 142 is energized, it generates a magnetic attraction force that drives the lens carrier 13 against the base 12. When the coil structure 142 is energized, the coil structure 142 generates a magnetic attraction force, and the coil structure 142 cooperates with the magnet structure 141 to lock the lens carrier 13.

[0073] Alternatively, as Figure 5 As shown, the magnet structure 141 is fixed to the side wall of the lens carrier 13 .

[0074] Optionally, Figure 6 This is a schematic diagram of the position of the magnet structure and coil structure of this application, such as Figure 6As shown, the centerlines of the magnet structure 141 and the coil structure 142 are both parallel to the base 12, and the vertical distance between the centerline of the magnet structure 141 and the base 12 is greater than the vertical distance between the centerline of the coil structure 142 and the base 12. In this embodiment, the centerline of the magnet structure 141 and the centerline of the coil structure 142 are not aligned horizontally. When the coil structure 142 is energized, it generates a downward pulling force, causing the lens carrier 13 to move toward the base 12 until it rests against the base 12.

[0088] 4. The camera locks the AF to telephoto and turns off the anti-shake function module;

[0089] Fifth, issuing a command to output current to the coil structure 142 , which generates a magnetic field when energized, thereby forming a magnetic attraction force to drive the lens carrier 13 ;

[0090] Sixth, the magnetic attraction formed by the coil structure 142 fixes the lens carrier 13 on the base 12, avoiding the inertial force generated by violent movement, which may cause the image to shake;

[0091] 7. The Super Sports video mode shooting ends, or the shooting mode is switched to another mode;

[0092] 8. Stop supplying power to the coil structure 142, and the focus function and anti-shake function modules return to normal;

[0094] Second embodiment

[0095] Figure 7 is a structural diagram of a camera device according to a second embodiment of the present application. Figure 8 : is a structural diagram of the lens carrier and the locking mechanism of the second embodiment of the present application. Figure 7 and Figure 8 As shown, the camera device of this embodiment is substantially the same in structure and function as the camera device of the first embodiment, except that the connection method between the locking mechanism 14 and the housing 16 is different.

[0096] Optionally, the locking mechanism 14 further includes a circuit board 143 and a housing 144. The coil structure 142 is electrically connected to the circuit board 143. The circuit board 143 is fixed in the housing 144. The housing 144 is detachably connected to the housing 16. In this embodiment, the locking mechanism 14 is a separate mechanism that can be separated from the housing 16 and exist independently. When needed, the locking mechanism 14 is mounted on the side wall of the housing 16. Because the side wall of the housing 16 has a certain barrier to the magnetic field, the size of the coil structure 142 of this embodiment can be designed to be larger, or the number of coil assemblies 142a can be increased. For example, the number of coil assemblies 142a in the first embodiment is 2, while the number of coil assemblies 142a in this embodiment is 4. The number of coil assemblies 142a can be freely increased or decreased according to actual needs.

[0097] The locking mechanism 14 of the present application is a separate module, and its production and manufacturing will not interfere with the production and assembly of other structures of the camera device. There is no need to perform special structural design and optimization on other structures of the camera device (including the housing 16, lens carrier 13, lens, intermediate carrier 17, and various coils and magnets 123), and no additional production design costs will be incurred.

[0098] Optionally, the housing 144 of the locking mechanism 14 and the outer shell 16 can be detachably connected by means of a slide groove and a slide rail, and the two can be fixed together by means of screws and screw holes or a locking structure. When the locking mechanism 14 needs to be installed, the slide groove and the slide rail are matched and combined, and the locking mechanism 14 is pushed to the appropriate position (the position when the housing 144 is aligned with the screw holes on the outer shell 16), and then the locking mechanism 14 and the outer shell 16 are fixed together using screws or other fasteners; when the locking mechanism 14 needs to be disassembled, the screws are removed, and then the locking mechanism 14 is slid to disengage the slide groove and the slide rail, and the disassembly is completed. Installation and disassembly are very quick and convenient.

[0099] Optionally, a window 301 is provided on the side of the housing 144 facing the outer shell 16, and the coil structure 142 is arranged corresponding to the window 301. In this embodiment, the magnetic attraction generated by the coil structure 142 when energized attracts the magnet structure 141 through the window 301. The design of the window 301 can prevent the housing 144 from blocking the magnetic field.

[0100] Third embodiment

[0101] Figure 9 : is a schematic structural diagram of the magnet structure and base of the third embodiment of the present application, as shown in FIG. Figure 9 As shown, the camera device of this embodiment has substantially the same structure and function as the camera device of the above embodiment, except that the local structures of the magnet structure 141 and the base 12 are different.

[0102] Optionally, the side wall of the magnet structure 141 is provided with at least one magnetic boss 1413, and the base 12 is provided with at least one elastic member 122, the elastic member 122 is connected to the magnet 123, the magnet 123 and the magnetic boss 1413 are arranged correspondingly, and the polarity of the magnet 123 and the magnetic boss 1413 are different; when the coil structure 142 is energized to drive the lens carrier 13 to move toward the direction close to the base 12, the magnet 123 and the magnetic boss 1413 can be attracted together, and the elastic member 122 relies on the elastic force to make the lens carrier 13 rest against the base 12. Since the lens carrier 13 can be moved a short distance toward the base 12 so that the magnet 123 and the magnetic boss 1413 can be adsorbed together, the elastic force of the elastic member 122 can drive the lens carrier 13 to be fixed on the base 12. Therefore, when the magnet 123 and the magnetic boss 1413 are adsorbed together, the current of the coil structure 142 is disconnected, which can save energy and avoid the problems of increased power consumption and increased temperature of the whole machine.

[0103] Alternatively, as Figure 9 As shown, the first locking magnet 1411 is located above the second locking magnet 1412, and the second locking magnet 1412 is closer to the base 12. The first locking magnet 1411 is provided with magnetic bosses 1413 at both ends along its length. When the polarity of the magnetic boss 1413 is the N pole, the polarity of the magnet 123 is the S pole.

The locking mechanism 14 further includes a controller for controlling the current of the coil structure 142. The controller is electrically connected to the accelerometer, and the controller is configured to adjust the current of the coil structure 142 according to the acceleration. When the camera device enters the super motion video stabilization mode in the video mode, the controller will first capture the value of the accelerometer, and adjust and modify the current value sent to the coil structure 142 in real time based on the value output by the accelerometer. A total of 23 current adjustable gears from 0 to 10 can be achieved, and the current value can be adjusted from 0 to -120mA and below, truly achieving infinite dynamic current adjustment, that is, achieving super motion video stabilization and also achieving the effect of low power consumption regulation.

[0106] Optionally, the magnitude of the acceleration is proportional to the magnitude of the current, that is, the greater the acceleration, the smaller the current value, and the smaller the acceleration, the smaller the current value.

[0107] The operating logic of the functional modules of the camera device of this application is as follows:

[0108] 1. Open the camera app;

[0109] Second, enter video recording mode;

[0110] 3. Select Super Sports video stabilization mode;

[0111] Fourth, the controller controls the output of different negative currents according to different acceleration values;

[0112] Fifth, the coil structure 142 outputs different pulling forces;

[0113] 6. Video recording ends.
